Krysyy hit the nail on the head, but I still feel like elaborating a teeny bit further :P

Basically, if you do something that seems impossible for a human to do, it's not allowed by default on EMC. The printer function of Schematica, for example, can be seen as a direct player advantage. Anything automated with little-to-no player interaction as such is disallowed.

I've had an alt banned before for afk fishing -- I want to bring that up because it's a perfect example of how unfair player advantage ties into automation and why that's disallowed. (It's also a personal example of me moving on and learning from it, looking back so I don't make the same mistake again.)

Oh I was just saying that the forum rules said that the buyer had 48 hours to pay unless agreed upon differently. Unfortunately, the way in which I said it caused a glitch that caused the thread to auto-redirect to the EMC wiki. I already figured out what exactly the bug was, and reported it to aikar and he fixed it.
